Research Profile


Isara is an energy-environmental researcher. She has background in Environmental Engineering. Her current research interest aligns within the field of environmental-energy analysis, GHG emissions accounting, macroeconomic analysis (Input-Output Analysis) and Life Cycle Assessment. Isara obtained her Bachelor and Master degrees in Environmental Engineering from Kasetsart University, and Chulalongkorn University in Thailand. She completed her Ph.D. in Environmental Engineering from National Cheng Kung University, Taiwan in January 2017. Her Ph.D. research focused on the integrated analysis of energy consumption and CO2 emissions, and Input-Output Life Cycle Assessment of the electricity generation sector in Thailand. Previously, Isara worked as a Postdoctoral Researcher at Solent University, Southampton, between 2018-2020. She engaged in the EU Interred, Two Seas funded, Ports Energy and Carbon Saving (PECS) Project. The main objective of PECS is to establish and implement different tools and technologies to reduce the carbon footprint of small to medium sized entrepreneurial ports, and their operations more energy efficient. Isara was a key resource in the development of methodologies to assess carbon footprint of entrepreneurial ports, calculating GHG emissions from port partners activities along with advising Portsmouth International Port to reduce GHG emissions.


Isara is passionate about emissions assessment, energy consumption and climate change impact. She joined the Research Centre for Carbon Solutions at Heriot-Watt University as Research Associate in order to gain knowledge in the area of Carbon Dioxide Removal Technologies, Ocean Alkalinity Enhancement and prospective life cycle assessment.
She is currently engaged in the Performance of Ocean Alkalinity Enhancement Technologies (POaET) project to develop a harmonised Life cycle assessment (LCA) and Techno-economic assessment (TEA) framework for Ocean Alkalinity Enhancement (OAE) to quantify and evaluate the potential environmental impacts of OAE approaches, and to exemplify integrated technoeconomic environmental (TEE) framework, and integrated prospective LCA.
